| Abstract: | The causes of work and backup roll failures of roughing mill of ASP of Jinan Iron ~ Steel Co. , Ltd. were analyzed. By reasonable design the angles of work and backup roll, the problem of shell fracture of shoulder of roll could be resolved. Meanwhile, based the roll material characteristics , roll grinding schedule was adjusted, and the inspecting and tracking of roll were assured. Therefore, the service life of roll could be in creased , and roll consumption be decreased. |
